BUTTON-FEEDING MECHANISM FOR. BUTTON-SETTING MACHINES.

. ting Machines; and I do hereby declare the following to be a full, clear, and exact des'cription of the invention, such as will enable others skilled in the art to whichit ap ertains to make and use the same.

Iy lnvention relates to button feeding.

mechanism for button setting machines, and more particularly to the type of machine having a vertically reciprocable guide to en-- gage the worlr opposite the anvll and a reciprocable driver movable in the guide to driy e the staple or fastener, and its object is to provide asimple and reliable automatic device adapted to be detachably secured to a machine of the type described,

and to rovide the same with various novel and use 'ul features as hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a machine of the type described with my deuce applied thereto; Fig.'2 an enlarged detail in. elevation of a portion of the button feeding mechanism; Fig. 3 a detail in side elevation showing the position of the parts at the close of the clenching movement of the machine;'Fig. 4 a plan view of the same, Fig. 5 a detail of the friction collar; Fig. 6a perspective detail of the button feeding .pusher; and Fig. 7 an enlarged detail of thesafety mechanism of the feeder.

Like numbers refer to like parts in all of the figures.

1 represents the frame of the machine. 2 a vertically reciprocable plunger operated by a rod 3 connected to a treadle (not shown). This plunger carries an integral laterally projecting plate ton which is'mounted a guide 5 adapted to receive the button and staple from the feeder and carry the same to position above the anvil 8. An upward extension of this guide 5 carries a friction collar 6 slidable thereon and provided,,,,with a screw for adjusting the same whereby the guide is frictionally held in contact gvith .thefabric as the plunger descends and is Specification of Letters Patent.

carried up against a fixedguide arm 7 on the frame andin position to receive another button and staple as the plunger rises. A staple driver 6.is also attached to the arm 4C and reciprocates in the guide to drive and clench the staple.

The, device so far described is or a well known construction. and needs no further explanation.

My lnvention resides in the button feeding mechanism hereinafter described, in which 10 is a chute having a bottom slot traversed by the eyes of the buttons and lateral channels traversed by the staples therein. 11 is a yieldable stop projecting into this chute from abo e 1e same and adapted to engage in succession the eyes of the button as they move down the chute, and yieldingly stop the same in proper position;

12 is a pusher having parallel sides spaced apart and adapted at the lowerfend-to embrace the eye of the button and engage the shoulders of the staple, as illustrated in F ig.

6. A pin 16 is fixed in the frame 9 close below this pusher and the latter is provided with an inclined projection 24 which engages the pin as the pusher is retracted and raises the lower end of the same to clear the .next succeeding button eye and pass above.

the same.

When many buttons are in the chute their .weight will usually cause the pusher to pass over the eye of the lower button but when thechute contains but few buttons the pusher may carry the buttons up the tube. This shoulder is so, located on the pusher that should the pusher carry the eye of the last button up the'tube away from the stop the shoulder will raise the pusher and release the eye which will then drop to place against the stop and below the pusher thus insuring accurate feeding at all times. This pusher 12 is reciprocated by a lever 17 oppositely projecting from its pivot which lever is operated to retract the pusher by an arm 18 connected to the lever by a yieldable spring 19 to move the pushed downward and having a lateral offset engaging the said lever to move the pusher upward. This arm 18 is reciprocated by a connecting rod 20 pivoted to a lever 21 which lever is moved upward to move the pusher down and feed a button at the termination of the up stroke of the plunger by a projection 22 on the I arm 4 and is oppositely moved at'the nation of the down stroke of the machine to move the pusher up into engagement with thenext succeeding button inthe chute by a {shoulder 23 on the, upper part of the plate 4.

A sprin 13. is attached to the pusher and yieldably oldsthe same in contact with the 2' der 25 which when the reaches itsupper position the projection 22- raises the, lever 21v and thus" forces the pin 16. This spring has an inclined shoulusher is retracted engages a rounded pro ection 14- on the frame and preventsfthe pusher from descending prematurely, 'As the guide nearly pusher down to feed the next button into the guide-which button when released from the stop 11 proceeds to place in the guide by gravity alone.

Should there be any unusual obstruction to the-feeding movement of the pusher the spring 19 will yield and avoid any breakage of the machine. The described feed mechanism is preferably mounted on a detachable frame 9 fixed at its lower end to the guide arm 7; What I claim is 1., In a button setting machine, button feeding mechanism, comprising a chute having a-slot to receive the eye of a button and side channels toreceive a button fastener, a

- pusher having parallel sides spaced apart and adapted at the lower end to embrace the 'eye of a button and engage the shoulders of a fastener, means for reciprocating the pusher, and a yieldable stop to engage the eye of a button and temporarily hold the.

same. 7

2. In a button setting machine, button setting mechanism, comprising a chute having a bottom slot to receive the eye of a button and side channels to receive a fastener, a pusher having parallel sides spaced apart' and having a downwardly projecting lower end adapted to embrace the eye of abut-ton andengage the shoulders of a fastener, 'a

. shoulder on the under side of the pusher, a

pin for engagement by the shoulder to raise the said lower end, means for reciprocating the pusher, and a yieldable stop to engage and temporarily hold the eye of the button. 3. In a button setting. machine, button feeding mechanism, comprising a chute having a bottom slot to receive the eye of D a button and side channels to. receive a butder to raise the end of the pusher, and a ,spring mounted on the pusher to yieldably ton fastener, a yieldable stop to engage the eye of a button and temporarily hold the same, a pusher having a bifurcated end adapted to embrace the eye of a button and.
